@PerfectSlayer @mhlidd I think this should not have tag: no release notes. It's a critical bug escalated by multiple users, and so it should be visible in release notes.

PerfectSlayer · 2025-06-27T10:22:52Z

Thanks for the heads-up, I removed id. I did not think it would be trigger in prod.
As it was, I really would like to have some tests around it to make sure we won't re-introduce the issue.

As it was, I really would like to have some tests around it to make sure we won't re-introduce the issue.

I agree. There were no tests for this initially because the escaper code was taken directly from OTEL, but was then modified because our use case was slightly different. The only time this is currently tested is through BaggagePropagatorTest when injecting/extracting headers but I can add unit tests for the PercentEscaper itself in a future PR.
